Shimohara, Georgette and Hikari are out on patrol when they find the whole lake near the base has frozen over!  It's an ice Neuroi!  They engage the enemy, but it's too cold, and freezes their units solid.  The Neuroi then proceeds to freeze the entire base!  With no one else able to launch, it's up to the three of them to take out this frozen foe.
I was so focused on beating the Neuroi...
...كنتُ أركّزُ على هزيمة النيوروي
Ich war so davon besessen,
diesen Neuroi zu vernichten.
No debí empeñarme en pelear.
No debí empeñarme en pelear.
Parce que j’ai voulu
détruire un Neuroi…
Perché volevo per forza abbattere il Neuroi!
Eu estava tão focada 
em ganhar dos Neuroi...
